Java語言可用于音頻錄制和存儲。Java錄音API支持音頻錄制和回放，可將音頻數據存儲在文件系統中或在網絡上進行流傳輸。

錄音存儲

try {
// 定義音頻錄制編碼格式
AudioFormat format = new AudioFormat(44100.0F, 16, 2, true, false);
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
// 獲取音頻輸入設備
TargetDataLine targetDataLine = (TargetDataLine) AudioSystem.getLine(info);
targetDataLine.open(format);
targetDataLine.start();
// 定義輸出文件
File audioFile = new File("record.wav");
// 創建音頻輸出流
AudioFileFormat.Type targetType = AudioFileFormat.Type.WAVE;
AudioInputStream audioInputStream = new AudioInputStream(targetDataLine);
AudioSystem.write(audioInputStream, targetType, audioFile);
} catch (Exception e) {
e.printStackTrace();
}
